Add arrow to a line
I need to draw airways for which arrow needs to be added to decide the direction of the airway. I am drawing the airways by importing sequence of points. Unable to insert arrows to describe the direction. Each segment has a direction (forward or backward) based on which I need to draw the arrow. Any help....Connected to this, when i import line features between set of points, these lines are shown as straight lines. I need them to be great circles... what setting is required ? Thanks in anticipation.
